mp6-EVA Board Driven Externally

Q Can the mp6-EVA board be driven by an external CLOCK signal?

As described in the mp6 manual the mp6‑OEM onboard the mp6‑EVA can be driven by an external CLOCK signal. The resulting pump-frequency will be a quarter of the original CLOCK signal. Please take into account to set the pulse-width of the frequency (duty cycle) at a level of 95% when operating at pump-frequencies lower than 25 Hz. The CLOCK signal has to be rectangular in shape. The high-level should be between 1.3 V and 5.0 V; the low-level between 0 V and 0.3 V.

Using a burst-mode to generate small reproducible dosings is also possible. By sending a burst sequence to the CLOCK input of the mp6‑EVA the mp6 generates a defined number of pump pulses. As a result the pumped volume will have the same amount with each burst.
